DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 15 The present invention provides a technical solution: a combined processing device for a single crystal furnace bottom plate, comprising: a machine tool housing 1, a clamping seat 2 being rotatably connected to the inner bottom surface of the machine tool housing 1, and a U-shaped bracket 3 being fixedly connected to the upper portion of the inner wall of the machine tool housing 1. It should be noted that: a rotating motor frame is fixedly connected to the bottom of the clamping seat 2, and an electric telescopic rod is fixedly connected between the bottom of the rotating motor frame and the inner bottom surface of the machine tool housing 1. The rotating motor frame drives the single crystal furnace bottom plate on the clamping seat 2 for rotational processing, and the electric telescopic rod can drive the rotating motor frame and the clamping seat 2 upward, so that the single crystal furnace bottom plate on the top of the clamping seat 2 is fitted with the bottom of the grinding sleeve 408 for grinding processing. The above-mentioned rotating motor frame, the clamping seat 2 and the electric telescopic rod are all existing technologies and will not be described in detail here.

[0019] The tool switching mechanism 4 is also included. The tool switching mechanism 4 is movably mounted on the upper portion of the U-shaped bracket 3 and is used to switch the processing mode.

[0020] A driving mechanism 5 cooperating with the tool switching mechanism 4 is movably installed at the lower part of the U-shaped bracket 3. The driving mechanism 5 is used to drive the tool switching mechanism 4 to slide along the track of the U-shaped bracket 3 to perform combined processing.

[0021] In this embodiment, Figures 1 to 15 As shown, the tool switching mechanism 4 includes: a processing motor 401, which is slidably mounted on the upper portion of the U-shaped bracket 3. The rotating end of the processing motor 401 is fixedly connected to a support cylinder 402. A milling cutter rod 403 is vertically mounted at the bottom of the support cylinder 402. A limit assembly 404 is movably mounted between the surface of the milling cutter rod 403 and the support cylinder 402. The limit assembly 404 is used to lock the position of the milling cutter rod 403 within the support cylinder 402. It should be noted that the milling process is performed by driving the support cylinder 402 and the milling cutter rod 403 in the limited state to rotate by the processing motor 401.

[0022] The outside of the support cylinder 402 is rotatably connected to a guide sleeve 405, and the two sides of the guide sleeve 405 are movably installed between the two sides of the inner wall of the U-shaped bracket 3. The surface of the milling cutter rod 403 is symmetrically fixedly connected to an adjustment pin 406, which penetrates the support cylinder 402 and is slidably set on the surface of the guide sleeve 405. The lower part of the support cylinder 402 is symmetrically hinged with a hinge rod 407, one end of the hinge rod 407 is hinged to the side wall of the milling cutter rod 403, and the other end of the hinge rod 407 is hinged to a grinding sleeve 408. It should be noted that when the milling cutter rod 403 moves downward inside the support cylinder 402, the grinding sleeve 408 is deflected upward on the outer wall of the milling cutter rod 403 under the cooperation of the hinge rod 407, switching the processing positions of the grinding sleeve 408 and the milling cutter rod 403, so that the milling cutter rod 403 moves downward to the original processing position of the grinding sleeve 408.

[0023] The inner wall of the U-shaped bracket 3 is symmetrically and movably connected with a trigger component 409 that cooperates with the limit component 404. The trigger component 409 cooperates with the limit component 404 to trigger and drive the tool switching mechanism 4 to operate.

[0024] In this embodiment, Figures 1 to 15 As shown, the limiting assembly 404 includes a conical ring 4041, which is movably mounted on the top of the support tube 402. The inner wall of the support tube 402 is symmetrically provided with vertical holes 4042. A pressure rod 4043 is vertically and movably mounted inside the vertical hole 4042. The top of the pressure rod 4043 is fixedly connected to the bottom of the conical ring 4041. It should be noted that the conical ring 4041 is movably sleeved on the rotating end of the processing motor 401. When the conical ring 4041 is compressed, it will move the pressure rod 4043 downward inside the vertical hole 4042.

[0025] The inner wall of the support cylinder 402 is symmetrically provided with pin holes 4044, and the two pin holes 4044 correspond one to one with the two vertical holes 4042. A limit pin 4045 is slidingly provided inside the pin hole 4044. The surface of the milling cutter rod 403 is provided with a limit hole 4046 that matches the limit pin 4045. The inside of the limit pin 4045 is provided with an inclined groove 4047, and the lower part of the pressure rod 4043 is slidingly provided inside the corresponding inclined groove 4047. It should be noted that: two limit holes 4046 are provided on both sides of the milling cutter rod 403. When the milling cutter rod 403 slides inside the support tube 402, the two limit holes 4046 cooperate with the limit pin 4045 on the same side to lock the position of the milling cutter rod 403 after movement; the lower part of the pressure rod 4043 is fixedly connected to a sliding pin, and the pressure rod 4043 is slidably arranged inside the corresponding inclined groove 4047 through the sliding pin, so that the pressure rod 4043 can move toward the pin hole 4044 with the limit pin 4045 during the downward movement.

[0026] The middle part of the inner wall of the vertical hole 4042 is movably connected with an extrusion spring, and the middle part of the pressure rod 4043 is fixedly sleeved with a pressure ring that matches the extrusion spring. It should be noted that when the cone ring 4041 is released from the compressed state, the extrusion spring brings the pressure rod 4043 and the cone ring 4041 up and back to the original position.

[0027] The support cylinder 402 is symmetrically provided with adjustment slots that cooperate with the adjustment pin 406. The guide sleeve 405 is symmetrically provided with a U-shaped slot that cooperates with the adjustment pin 406. A trapezoidal reset block 4048 that cooperates with the adjustment pin 406 is symmetrically fixedly connected to the right side of the inner wall of the U-shaped bracket 3. It should be noted that when the guide sleeve 405, carrying the support cylinder 402 and the milling cutter rod 403, moves to the right side of the U-shaped bracket 3 to the extreme position and completes the processing, the adjustment pin 406 slides along the surface of the trapezoidal reset block 4048, allowing the milling cutter rod 403, which has been unlocked, to rise inside the support cylinder 402 and return to its initial position.

[0028] In this embodiment, Figures 1 to 15As shown, the trigger assembly 409 includes a transmission screw 4091, and there are two transmission screws 4091. The two transmission screws 4091 are symmetrically connected to the two sides of the inner wall of the U-shaped bracket 3. The surface of the transmission screw 4091 is threadedly connected to the trigger sleeve 4092, and the surface of the trigger sleeve 4092 is slidably set on the inner wall position of the U-shaped bracket 3. The end of the trigger sleeve 4092 is provided with a groove 4093, and the inside of the groove 4093 is hinged with a push rod 4094 that cooperates with the cone ring 4041. It should be noted that a torsion spring is fixedly connected between the inner wall of the groove 4093 and the surface of the push rod 4094. When the support cylinder 402 moves from left to right with the cone ring 4041, the push rod 4094 will not flip inside the groove 4093 and press the cone ring 4041 to move downward on the surface of the support cylinder 402 under the restriction of the groove 4093. When the support cylinder 402 moves from right to left with the cone ring 4041, the cone ring 4041 contacts the push rod 4094, and the push rod 4094 can move in the groove. 4093 deflects internally, and at this time the push rod 4094 cannot press the cone ring 4041 to move downward on the surface of the support tube 402, so that the push rod 4094 can only squeeze the cone ring 4041 in one direction to operate; an adjustment knob is provided at the left end of the transmission screw 4091, and the adjustment knob can be replaced by an adjustment motor, which is used to drive the transmission screw 4091 to rotate, so that the trigger sleeve 4092 can translate inside the U-shaped bracket 3, and adjust the trigger switching position of the milling cutter rod 403 and the grinding sleeve 408 during the movement of the guide sleeve.

[0029] A one-way sleeve 4095 is fixedly connected to the bottom of the trigger sleeve 4092. A wedge-shaped rod 4096, which cooperates with the drive mechanism 5, is rotatably connected to the interior of the one-way sleeve 4095. It should be noted that the cooperation between the one-way sleeve 4095 and the wedge-shaped rod 4096 is based on the same principle as the cooperation between the trigger sleeve 4092 and the push rod 4094, so that the wedge-shaped rod 4096 can only cooperate with the drive mechanism 5 in a single direction. This will not be further described here.

[0030] A one-way reset rod 4097 is symmetrically fixedly connected to the right side of the U-shaped bracket 3 , and the one-way reset rod 4097 has the same structure as the trigger sleeve 4092 and the push rod 4094 .

[0031] In this embodiment, Figures 1 to 15 As shown, the grinding sleeve 408 is mounted on the surface of the milling cutter rod 403. A limit ring is fixedly mounted on the middle portion of the milling cutter rod 403. A compression spring is fixedly connected between the top of the limit ring and the bottom of the support tube 402. It should be noted that when the limit hole 4046 on the milling cutter rod 403 is disconnected from the limit pin 4045 inside the support tube 402, the compression spring rapidly moves the limit ring and the milling cutter rod 403 downward, switching the position of the milling cutter rod 403 and the grinding sleeve 408.

[0032] The bottom of the support tube 402 is symmetrically fixed with an L-shaped hinge bar. A waist-shaped groove is defined in the middle of the hinge rod 407, which is hingedly mounted to the lower portion of the L-shaped hinge bar via the waist-shaped groove. The surface of the milling cutter rod 403 and the inner wall of the grinding sleeve 408 are both fixedly connected with hinge blocks, and the ends of the hinge rod 407 are respectively hingedly mounted to the two hinge blocks. It should be noted that a support bearing is fixedly connected between the lower portion of the support tube 402 and the inner wall of the guide sleeve 405. This ensures that the support tube 402 does not rotate with the guide sleeve 405 during rotation, thus avoiding interference.

[0033] In this embodiment, Figures 1 to 15 As shown, the drive mechanism 5 includes a drive motor 501, which is slidably mounted on the lower portion of the inner wall of the U-shaped bracket 3. The rotating end of the drive motor 501 is fixedly connected to a ball-end telescopic rod 502 that cooperates with the wedge-shaped rod 4096. The upper portion of the ball-end telescopic rod 502 passes through the guide sleeve 405 and is movably connected to a return spring 503. It should be noted that the ball-end telescopic rod 502 can only be extended and retracted, and cannot rotate on its own. The ball-end telescopic rod 502 can only be rotated by the drive motor 501.

[0034] The middle part of the ball-end telescopic rod 502 is fixedly sleeved with a transmission gear 504, the inner wall of the U-shaped bracket 3 is slidably connected to a U-shaped screw frame 505, the lower part of the guide sleeve 405 is threadedly connected to the surface of the U-shaped screw frame 505, the lower part of the U-shaped screw frame 505 is fixedly sleeved with a matching gear 506 that matches the transmission gear 504, and the right side of the inner wall of the U-shaped bracket 3 is fixedly connected to a reset rack 507 that matches the matching gear 506. It should be noted that: ear plates are provided on both sides of the guide sleeve 405, the ball-end telescopic rod 502 is movably inserted into the surface of the corresponding ear plate, and one end of the ear plate is threadedly connected to the surface of the corresponding U-shaped screw frame 505; when the U-shaped screw frame 505 rotates, the ear plate will carry the guide sleeve 405 up and down on the surface of the U-shaped screw frame 505; when the guide sleeve 405 moves inside the U-shaped bracket 3, the matching gear 506 meshes with the transmission gear 504 and carries the guide sleeve 405 on the U-shaped After the surface of the screw rack 505 moves downward, when the guide sleeve 405 moves to the right to the extreme position, the mating gear 506 engages with the reset rack 507, so that the guide sleeve 405 can move up and reset. The reset rack 507 is set to a one-way rack type. When the mating gear 506 moves from right to left, the teeth of the reset rack 507 will shrink and cannot engage for transmission; a countersunk hole is provided at the bottom of the ear plate to cooperate with the transmission gear 504 to avoid interference caused by the transmission gear 504 in the reset rising state.

[0035] The lower portion of the ball-end telescopic rod 502 is fixedly sleeved with a main drive gear 508, and the bottom of the main drive gear 508 is provided with a slave drive gear 509, which is slidably mounted on the surface of the ball-end telescopic rod 502. The lower portion of the ball-end telescopic rod 502 is movably sleeved with a push spring 510 that cooperates with the slave drive gear 509. The top of the slave drive gear 509 is overlapped with an arc-shaped switching rod 511, and the top of the arc-shaped switching rod 511 is fixedly connected to the surface of the guide sleeve 405. It should be noted that the surface of the drive motor 501 is fixedly connected to a movable frame, which is slidably mounted on the inner wall of the U-shaped bracket 3. When the drive motor 501 rotates with the ball-end telescopic rod 502 and the main drive gear 508, the main drive gear 508 engages with the main drive rack 512. At this time, the drive motor 501 slides along the side wall of the U-shaped bracket 3 with the guide sleeve 405 and the U-shaped screw frame 505 through the ball-end telescopic rod 502.

[0036] The inner wall of the U-shaped bracket 3 is fixedly connected with a main drive rack 512 that matches the main drive gear 508, and a slave drive rack 513 that matches the slave drive gear 509 is provided below the main drive rack 512. It should be noted that: during use, when the ball-head telescopic rod 502 is not squeezed by the wedge rod 4096, the main drive gear 508 on the ball-head telescopic rod 502 is meshed with the slave drive gear 509 for transmission. When the wedge rod 4096 squeezes the top of the ball-head telescopic rod 502, the ball-head telescopic rod 502 contracts, causing the transmission gear 504 to move downward and mesh with the matching gear 506. Then, the guide sleeve 405 moves downward, which will bring the arc-shaped switching rod 511 to press the slave drive gear 509 downward and mesh with the slave drive rack 513 for transmission. In this process, the guide The sleeve 405 stops the translation of the milling rod 403 after the switching state, and drives the milling rod 403 downward to perform milling processing on the surface of the furnace bottom plate. Then, when the slave drive rack 513 and the slave drive gear 509 are engaged in transmission, the guide sleeve 405 continues to translate the milling rod 403 to the right, so that the ball head telescopic rod 502 is released from the squeezed state with the wedge rod 4096, and the main drive gear 508 after rising and resetting is engaged with the main drive rack 512 again, and the milling rod 403 in the downward milling state continues to translate to the right for milling processing.

[0037] In this embodiment, Figures 1 to 15As shown, the distance from the top of the main drive gear 508 to the bottom of the main drive rack 512 is the same as the distance from the bottom of the transmission gear 504 to the middle of the mating gear 506. It should be noted that when the top of the ball-end telescopic rod 502 is pressed downward by the wedge rod 4096, the ball-end telescopic rod 502 disengages the main drive gear 508 from the main drive rack 512, while the transmission gear 504 engages with the mating gear 506 for transmission. At this time, the screw inside the U-shaped screw rack 505 rotates, allowing the guide sleeve 405 to move downward. Then, the downward-moving guide sleeve 405 pushes the slave drive gear 509 to move downward on the surface of the ball-end telescopic rod 502 through the arc-shaped switching rod 511. When the guide sleeve 405 is about to When it moves down to the extreme position, the slave drive gear 509 engages with the slave drive rack 513, causing the guide sleeve 405 to move to the right. At this time, the ball head telescopic rod 502 releases contact with the wedge rod 4096, and the return spring 503 brings the ball head telescopic rod 502 up and resets, causing the transmission gear 504 to disengage from the matching gear 506, and the guide sleeve 405 stops moving down. The main drive gear 508 that has moved up engages with the main drive rack 512 again, causing the guide sleeve 405 to continue to move to the right with the milling cutter rod 403 after switching the state.

[0038] In this embodiment, Figures 1 to 15 As shown, the upper portion of the inner wall of the U-shaped bracket 3 is symmetrically provided with movable grooves. A support bar is fixedly sleeved on the surface of the processing motor 401. Both ends of the support bar are fixedly connected to a telescopic movable pin. The support bar is slidably arranged inside the corresponding movable groove through the telescopic movable pin. It should be noted that the telescopic movable pin cooperates with the movable groove. When the guide sleeve 405 moves downward with the support cylinder 402 and the locked milling cutter rod 403, the telescopic movable pin can produce a contraction effect to avoid interference. The use method and advantages of the present invention: The combined processing equipment for the bottom plate of a single crystal furnace has the following working process: like Figures 1 to 15 As shown, when in use, first drive the transmission screw 4091, adjust the positions of the trigger sleeve 4092 and the push rod 4094, then start the clamping seat 2 to rotate and rise the clamped furnace bottom plate to the bottom position of the grinding sleeve 408, during which the processing motor 401 is started to rotate the support cylinder 402, the milling cutter rod 403 and the grinding sleeve 408, then start the driving motor 501 to drive the ball head telescopic rod 502 and the main driving gear 508 to engage with the main driving rack 512, and the ball head telescopic rod 502 drives the guide sleeve 405 to translate to the right at a low speed inside the U-shaped bracket 3, at this time, the surface of the rotating furnace bottom plate is polished by the grinding sleeve 408; When the guide sleeve 405 moves to the position of the trigger sleeve 4092, the push rod 4094 at the end of the trigger sleeve 4092 contacts the cone ring 4041 at the top of the support tube 402, so that the cone ring 4041 is compressed and moves with the pressure rod 4043 to the inside of the inclined groove 4047 of the limit pin 4045. At this time, the limit pin 4045 slides into the pin hole 4044 and releases the plugging with the corresponding limit hole 4046. Under the action of the compression spring, the compression spring brings the limit pin 4045 into contact with the cone ring 4041 at the top of the support tube 402. The positioning ring and the milling cutter rod 403 move downward inside the support cylinder 402. When the milling cutter rod 403 moves downward to the limit position, the limiting hole 4046 on the upper part of the milling cutter rod 403 moves to the position of the limiting pin 4045. When the push rod 4094 contacts the cone ring 4041, the extrusion spring drives the pressure rod 4043 to reset and move the limiting pin 4045 to reset and insert into the corresponding limiting hole 4046, thereby locking the milling cutter rod 403 after it moves downward. During the downward movement of the milling cutter rod 403, the hinged rod 407 on the milling cutter rod 403 rotates with the bottom of the L-shaped hinge bar as a fulcrum, so that the end of the hinged rod 407 and the hinged grinding sleeve 408 rise, switching the processing positions of the grinding sleeve 408 and the milling cutter rod 403, and the milling cutter rod 403 moves downward to the grinding position of the grinding sleeve 408 for subsequent milling processing; During this process, the wedge-shaped rod 4096 at the bottom of the trigger sleeve 4092 presses against the top of the vertically sliding ball-end telescopic rod 502 on the surface of the guide sleeve 405, causing the ball-end telescopic rod 502 to contract after being compressed. At this time, the ball-end telescopic rod 502 moves down with the main drive gear 508 to release the meshing with the main drive rack 512. At the same time, the transmission gear 504 on the ball-end telescopic rod 502 moves down to the position of the matching gear 506 to engage the transmission, causing the screw inside the U-shaped screw rack 505 to rotate and move the guide sleeve 405 downward. The guide sleeve 405 moves the milling cutter rod 403 with the switched position downward for milling processing. When the guide sleeve 405 is about to move down to the limit position, the guide sleeve 405 The arc-shaped switching rod 511 at the bottom presses the slave drive gear 509 downward and meshes with the slave drive rack 513. As the ball-end telescopic rod 502 rotates with the slave drive gear 509, the guide sleeve 405 can continue to move to the right. At this time, the ball-end telescopic rod 502 is released from contact with the wedge rod 4096. Then the return spring 503 lifts the ball-end telescopic rod 502 and resets it, so that the upward-moved transmission gear 504 is released from meshing with the mating gear 506. The upward-moved main drive gear 508 meshes with the main drive rack 512 again, so that the ball-end telescopic rod 502 continues to move the guide sleeve 405 to the right, so that the downward-moved milling cutter rod 403 completes the milling process. When the guide sleeve 405 moves with the milling cutter rod 403 to the center of the furnace bottom plate, the cone ring 4041 on the top of the support cylinder 402 contacts the one-way reset rod 4097 and is pressed downward, so that the milling cutter rod 403 is unlocked from the support cylinder 402 again. At the same time, the trapezoidal reset block 4048 cooperates with the adjustment pin 406 on the milling cutter rod 403 to slide, so that the milling cutter rod 403 rises inside the support cylinder 402. When the cone ring 4041 passes over the one-way reset rod 409 7 position, the limit pin 4045 is in the reset state, so that the limit hole 4046 at the lower position of the milling cutter rod 403 after continuing to rise can be plugged and locked with the limit pin 4045. At the same time, as the milling cutter rod 403 rises and resets, the hinged rod 407 moves down with the grinding sleeve 408 and resets to the initial state, and the matching gear 506 on the synchronously moving U-shaped screw frame 505 engages with the reset rack 507 for transmission, so that the guide sleeve 405 rises and resets to the initial state.
